Opened: Apr 29, 2018
Severity: 4-Minor

Symptoms

- Extractions are added to parameters in manual mode. - In manual learning mode on 'fallback to default' URL classification is not ended properly (resulting in repetitive audit log attempts to end URL classification). - In manual learning mode on 'fallback to default', parameter staging is set to true. - The system writes errors to pabnagd.log.

Impact

- URL content types are not enforced in manual mode. - Parameters are getting staged automatically in manual mode. - Parameters are classified as dynamic (value type). - Extractions are added to dynamic parameters

Conditions

- Manual learning mode. - Classification is on for either parameters or URLs. - Any option of 'Learn Dynamic Parameters' is turned on (even if checkbox is disabled).

Workaround

- Update the URLs manually (any update will take them out of classification). - Manually unstage parameters with 'fallback to default'. - Unset parameters' dynamic value type (or uncheck all parameters' dynamic classification options in 'Learning And Blocking Settings').

Fix Information

- URLs end classification successfully on 'fallback to default' in manual mode. - Parameters staging is not changed on 'fallback to default' in manual mode. - Parameters are not classified as dynamic in manual mode. - Extractions are not added to dynamic parameters in manual mode. - No errors in pabnagd.log.
